Methods: Data of 129 patients with histopathologically confirmed PTC were retrospectively reviewed in our study (90 in training group and 39 in testing group). ‘Radiomics’ is a novel process to identify ‘radiome’ in the field of imaging informatics when long-term clinical outcomes such as mortality are not immediately available, relying on first acquiring paired gene expression data and medical images at diagnosis from a study cohort, and then leveraging the public gene expression data containing clinical outcomes from a closely matched population into a … Instead of taking a picture like a camera, the scans produce raw volumes of data which must be further processed to be usable in medical investigations. Studies in the active field of image‐derived markers (i.e., “radiomics”) strongly suggest that tomographic images do indeed embed more prognostic information than may be seen by an unassisted human eye.4-8 In order to be widely generalizable and have meaningful clinical use, it is essential that reproducibility of features can be tested in phantoms,9, 10 in addition to validating models in human subjects across different settings and multiple independent institutions.11-13. Lastly, while we have started with CT as the most commonly available imaging modality in our field, we intend to expand this collection to include positron emission tomography (PET) and magnetic resonance imaging (MRI). … In radiation oncology, radiomics studies have been published to explore different clinical outcome in lung (n=5), head and neck (n=5), esophageal (n=3), rectal (n=3), pancreatic (n=2) cancer and brain metastases (n=2). The dataset is hosted in a well‐established and publicly funded XNAT instance. Radiomics reproducibility may be investigated as a function of: scanner manufacturer/scanner type, slice thickness, tube current (i.e., signal to noise ratio), and reconstruction algorithms. The images of the Catphan 700 quality assurance phantom from each center were analyzed online on the quality assurance tests webpage of the ImageOwl company (https://catphanqa.imageowl.com/). Below is a list of such third party analyses published using this Collection: The DICOM Radiotherapy Structure Sets (RTSTRUCT) and DICOM Segmentation (SEG) files in this data contain a manual delineation by a radiation oncologist of the 3D volume of the primary gross tumor volume ("GTV-1") and selected anatomical structures (i.e., lung, heart and esophagus). We scanned Model 057A that simulated the abdomen of a small adult. Dirk de Ruysscher, MAASTRO (Dept of Radiotherapy), Maastricht University Medical Centre+, Maastricht, Limburg, The Netherlands. https://doi.org/10.7937/K9/TCIA.2015.PF0M9REI, Aerts, H. J. W.

The COPDGene Phantom II (Phantom Laboratory, Greenwich, NY, USA) was designed for thoracic CT quality assurance in prospective clinical trials (specifically asthma and chronic obstructive pulmonary disorder) with guidance from the Quantitative Image Biomarker Alliance Technical Committee. Of note, DICOM SEG objects contain a subset of annotations available in RTSTRUCT. The handcrafted radiomics approach involves manual segmentation of the region of interest (eg, the tumour) on medical imaging, and extraction of thousands of human-defined and curated quantitative features from the region of interest, which describe tumour shape and texture among other characteristics. Data Usage License & Citation Requirements. This dataset refers to the Lung1 dataset of the. Computer‐aided analysis of clinical radiological images offers a data‐at‐large‐scale approach toward personalized medicine1 wherein tumor phenotype may be inferred using images of the entire tumor instead of selective sample biopsies. It is expected that radiomics takes an essential role in the current clinical oncology workflow, given that can be acquired noninvasively, and with no extra cost at any time of the treatment procedure. Ordering information D2071A DACT Three-zone communicator transmitter. Most studies were done for diagnosis and/or characterization (65%, 11/17) or to aid in prognosis (41%, 7/17). It is highly desirable to include only reproducible features into models, to be more assured of external validity across hitherto unseen contexts. This collection may not be used for commercial purposes. Nature Communications. NCI Imaging Data Commons consortium is supported by the contract number 19X037Q from Leidos Biomedical Research under Task Order HHSN26100071 from NCI. DICOM patients names are identical in TCIA and clinical data file. Recent … Radiomics is a science that investigates a large number of features from medical images using data-characterisation algorithms, with the aim to analyse disease characteristics that are indistinguishable to the naked eye. If you have a publication you'd like to add, please contact the TCIA Helpdesk. This was done in conjunction with MICCAI 2016 satellite symposium using Kaggle-in-Class, a machine-learning and predictive analytics platform. Added missing structures in SEG files to match associated RTSTRUCTs. The SFORCE … We chose to start with CT since this modality is readily available in many centers and is a workhorse imaging modality for radiotherapy intervention planning. Images, Segmentations, and Radiation Therapy Structures (DICOM, 33GB). Used in parallel or in addition to conventional biomarkers from biopsy and clinical data, radiomics is currently a major research topic for the development of personalized medicine, as all digitized images obtained in medical imaging can benefit from radiomics analysis based on the principle of texture. 1. The dataset is offered to the radiomics community to compare simple features extracted with different software pipelines as well as to identify features that may not be stable with respect to image acquisition conditions even under highly simplified conditions. Radiomic data contain first-, second-, and higher-order statistics. Use the link below to share a full-text version of this article with your friends and colleagues.

Data were collected at three Dutch medical centers: MAASTRO Clinic (Maastricht, NL), Radboud University Medical Center (Nijmegen, NL), and University Medical Center Groningen (Groningen, NL) with scanners from two different manufacturers Siemens Healthcare and Philips Healthcare. In short, the publication used a radiomics approach to computed tomography data of 1,019 patients with lung or head-and-neck cancer. All images and annotations were then exported as Digital Imaging and Communications in Medicine (DICOM)‐Radiotherapy (RT) objects. We subsequently applied perturbations to imaging settings of the baseline scan. Existing radiomics methods, however, require complex manual effort including the design of hand-crafted radiomic features and their extraction and selection. Working off-campus? A python script for downloading an entire collection is available here: (https://github.com/maastroclinic/XNAT-collections-download-script).

This collection consists of 17 CT scans of the Credence Cartridge Radiomics (CCR) phantom, which was designed for use in studies of texture feature robustness. The images used in our study were acquired using three different CT scanners at independent Dutch centers: MAASTRO Clinic (Maastricht), Radboud University Medical Center (Nijmegen) and University Medical Center Groningen (Groningen). Our scans are made open access via an instance of the Extensible Neuroimaging Archive Toolkit (XNAT) hosted within Dutch national research infrastructure (TraIT, www.ctmm-trait.nl).23 XNAT is an open source platform for imaging‐based research and clinical investigations, which manages access to different datasets compartmentalized into separate projects (i.e., collections). Studies have shown that feature reproducibility may be affected by differences in image acquisition parameters, such as slice thickness and reconstruction algorithm.14-17 Since clinical image acquisition protocols are one of the major sources of variation among different hospitals, phantoms allow testing, comparison, and harmonization of radiomic features in similar vein to diagnostic imaging quality assurance. 3 However, the main issue and challenging for the clinical applicability of the radiomics is the reliability and repeatability of the radiomics features 4 across multi‐centers. The following acquisition parameter were varied in the phantom scans: slice thickness, reconstruction kernels, and tube current.
